Shortly before Christmas of 1978, a teenage boy disappeared from the drugstore where he worked. He would be the final victim of John Wayne Gacy's horrifying compulsion. Then, ten days after the boy's disappearance. Detectives, finding a human bone in the crawl space of Gacy's house, dug into the lime-covered ground. With mounting horror, they pulled bone after bone from Gacy's suburban home until finally they had gathered the remains of twenty-eight more youths who had fallen prey to the killer clown.
